Product details
Overview
DMN3190LDWQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, rated for 30V VDSS, 190mΩ RDS(ON) at VGS = 10V and 1A ID, qualified to AEC-Q101 for automotive use in motor control and DC-DC converters.
For engineers reviewing the DMN3190LDWQ-13 datasheet, DMN3190LDWQ-13 pinout, DMN3190LDWQ-13 application, or DMN3190LDWQ-13 equivalent, key selection criteria include dual-channel low-RDS(ON) performance at 4.5V gate drive, AEC-Q101 qualification, thermal resistance (RθJA = 320°C/W), and SOT363 footprint compatibility with space-constrained automotive modules.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SOT363 package, each featuring independent gate terminals and shared source connections per channel (S1/G1/D1 and S2/G2/D2). Its design supports synchronous rectification and half-bridge configurations with fast switching (tR = 8.9ns, tF = 15.6ns) and low input capacitance (Ciss = 87pF).
The device operates across –55°C to +150°C junction temperature range, with gate threshold voltage VGS(TH) tightly specified (1.5–2.8V) and on-resistance stable over temperature (±20% variation up to 125°C). ESD protection on both gates (HBM >2kV) enables robust handling in automated assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum drain-source blocking voltage for 12V automotive rail applications |
| RDS(ON) @ VGS = 10V | 190mΩ - Enables <190mW conduction loss at 1A continuous current |
| RDS(ON) @ VGS = 4.5V | 335mΩ - Supports logic-level drive from 3.3V/5V microcontrollers in load switch designs |
| ID (max, TA = 25°C) | 1A - Continuous current rating under standard PCB mounting (1"×1", 2oz Cu) |
| Ciss | 87pF - Low input capacitance reduces gate drive power and improves switching efficiency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON) (25mΩ @ 10V), higher ID (3.8A), larger SOT23-6 package | Requires more PCB area; better suited for higher-current DC-DC stages | Select when >1.5A continuous current or <50mΩ conduction loss is required |
| NTJD4152PZ-1 | Higher RDS(ON) (420mΩ @ 4.5V), same SOT363, no AEC-Q101 qualification | Lacks automotive qualification and PPAP support; limited to industrial/commercial use | Choose only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with DMN3190LDWQ-13, DMN3025LSD-13 delivers significantly lower conduction loss but sacrifices compactness, while NTJD4152PZ-1 offers identical footprint at the cost of reliability validation and higher on-resistance-making DMN3190LDWQ-13 the optimal balance of size, performance, and automotive compliance.

FAQ
What is the maximum junction temperature for continuous operation?
The DMN3190LDWQ-13 has an operating junction temperature range of –55°C to +150°C. For continuous operation at full rated current (1A), thermal design must ensure junction temperature remains ≤150°C, typically requiring derating above +70°C ambient per the 0.19W power limit and 320°C/W RθJA.
Does this part support parallel operation of both channels?
Yes-both N-channel MOSFETs are monolithically integrated but electrically isolated, allowing independent or paralleled use. When paralleled, matched RDS(ON) and thermal coupling ensure balanced current sharing; however, separate gate resistors are recommended to prevent oscillation during switching transitions.
Is the SOT363 package lead-free and RoHS compliant?
Yes-the DMN3190LDWQ-13 uses matte tin annealed over Alloy 42 leadframe, fully compliant with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It contains no intentionally added lead, halogens, or antimony, meeting Diodes Incorporated's "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
Can this MOSFET be used in high-frequency PWM applications?
Yes-the device supports PWM frequencies up to 500kHz due to low gate charge (Qg = 2.0nC @ 10V), fast switching times (tR = 8.9ns, tF = 15.6ns), and low Ciss (87pF). Optimal performance requires proper gate driver impedance matching and minimized PCB loop inductance.
